BACKGROUND

The traditional measures of building performance are limited, primarily,to the measurement of energy usage through energy management systemsand/or building automation systems. Energy usage can be a large expensein large commercial facilities that include many buildings. In suchfacilities, energy usage can cost millions of dollars per year. Thechallenge in managing these facilities is to minimize the costs and tomaintain traditional building performance at acceptable levels.

Building designers, owners, and operators must consider other economicand environmental factors, including Indoor Air Quality (IAQ). IAQrefers to the air quality within and around buildings and structures. Inparticular, an analysis of IAQ can be used to assess indoor airpollution and the potential health risks that such pollution poses forbuilding occupants. The assessment of IAQ can help building ownersunderstand and control common indoor pollutants to reduce buildingoccupant health concerns.

More recently, the need to assess economic and environmental factors hasexpanded beyond the assessment of energy usage and IAQ to include ananalysis of Indoor Environmental Quality (IEQ). IEQ relates toenvironmental conditions inside of a building. Assessing IEQ can includeevaluating air quality, lighting, views, acoustic conditions, and manyother factors. Building managers and operators can increase thesatisfaction of building occupants by considering all of the aspects ofIEQ rather than narrowly focusing on temperature or air quality alone.

The development of sophisticated computerized energy management systemshas provided buildings owners with a variety of new tools that can beused to analyze various aspects of facility operations. These systemscan monitor energy usage over time, but they typically comparetraditional metrics of buildings performance to historical measurementsof building performance, essentially measuring the building againstitself. Additionally, these metrics are essentially limited to SiteEnergy Utilization Intensity (EUI), Source Energy Utilization Intensity(EUI), Cost of Utilities and Greenhouse Gas Emissions (CO2).

Moreover, these traditional metrics are measured annually and only aftera building is operational. This is undesirable because EUI is determinedafter the building has been operational for some period of time, usuallyconsidered to be twelve months. By that time, construction stakeholdershave typically exited the project. Since building owners, both forprofit and not for profit, cannot afford to wait for twelve months toacquire the trended data that is necessary to obtain a base levelcontext for traditional building performance, these existing energymanagement systems, when used to assess building performance againstdesign, are inadequate.

Buildings consume over 50% of the US energy and have no performancestandards that are typically considered during the planning or designphase of construction. Sustainability programs in the built environmentare typically prescriptive processes designed to raise awareness. Onlyrecently have sustainability programs started defining acceptablethresholds or ranges of performance for certain types of metrics.However, these sustainability programs provide limited, if any,direction on how to cost effectively achieve the performance-orientedrequirements, making the adoption of these new programs difficult toscale.

Existing energy management systems do not allow building owners toassess actual building performance compared to project goals set duringdesign due to the fragmented nature of commercial construction.Moreover, such systems are not sophisticated enough to measure afull-range of building performance factors as they relate to projectgoals. For these reasons there is a need for a holistic system forsetting performance goals during planning and measuring performanceagainst those goals in real-time during operations.

Referring to FIG. 1, various features of the subject disclosure are nowdescribed in more detail with respect to an integrated buildingperformance assessment system, generally designated as 100. The system100 addresses the above-described long felt need and allows buildingowners to assess building performance against project goals establishedduring planning. The system 100 assesses building performance within amore expanded context, such that the relevant building performancemetrics include metrics relating to energy usage, IAQ and IEQ. Thesystem 100 defines high performance buildings as any building, group ofbuildings, sites and/or communities whose performance achieves orexceeds performance targets set during pre-planning, planning,conceptual planning, design, etc.

The system 100 relates, generally, to a system that provides a holisticapproach to evidence-based performance in the built environment. Thesystem 100 provides building owners and facility managers with the toolsand the data necessary to assess, dynamically, building performanceversus the targets set in planning and/or design phases of a project.Stakeholders can use the system 100 throughout the building cycle in amanner that is aligned to deliver common goals, as set in planning.

The system 100 can include a computer system that can configure andimplement a virtual data acquisition component 110 that includes one ormore virtual data input devices 112, a virtual performance modelgenerator 114, and one or more data transmission devices 116.Additionally, the system 100 can configure and implement a physical dataacquisition component 120 that includes one or more physical data inputdevices 122 and one or more data transmission devices 124. The virtualdata acquisition component 110 and the physical data acquisitioncomponent 120 can connect to an integrated interface 130.

The integrated interface 130 has the ability to assess environmentalimpact of energy and indoor environmental quality performance for abuilding or a group of buildings. The integrated interface 130 measuresactual performance in real-time as a function of the financial andsocial goals of the building owner. These goals can be determined duringa planning phase or at another time thereafter.

The integrated interface 130 has the ability to display, visually,actual building performance data versus the goals set during theconstruction planning process. The integrated interface 130 utilizeshardware, software and proprietary knowledge to show buildingperformance within the context of an investment thesis for a buildingowner. The integrated interface 130 utilizes whole building energymodels and building goals that can be developed during the planningprocess. These models can be revisited or tracked, routinely, once abuilding is in operation. In this exemplary embodiment, the models canpredict various indicators of building performance, including metricsfor site EUI, source EUI, cost, carbon emissions and/or other greenhousegas emissions.

The integrated interface 130 provides building owners with transparencywith respect to the delivery of expected building performance during theconstruction process.

The information can be obtained manually or through automateddata acquisition methods or systems.

The virtual performance model generator 114 can utilize theabove-described information to generate a virtual building performancemodel having a plurality of predicted building performance metrics. Thevirtual building performance model can include predicted biometrics,predicted IAQ/IEQ, and/or predicted utility consumption. The predictedutility consumption can be categorized by sources, includingcogeneration systems, district energy chilled-water, district energysteam, electric, gas, potable water, renewable geothermal, renewablephotovoltaics, renewable wind, and/or one or more other types ofutility. The virtual building performance model can be a design model oran operational model depending upon when it is generated or modified.

The calculator can identify the value associated withoperational benefit, the social cost of carbon benefits, asset valuationbenefits, and/or occupant benefits.

The calculator can be a tool for predicting and validating the savingsassociated with EUI and IEQ improvements as a function of investmentcosts. The calculators can provide a holistic view of return oninvestment for energy conservation and IEQ related investments.

The building performance assessment platform 132 can utilize thedashboard display 138 to provide output for visually assessing aplurality of key performance indicators for a building. The dashboarddisplay 138 can provide output to enable visual identification of therelationship between trended and predicted building performance, whichcan enable the comparison of predicted building performance metrics withtrended building performance metrics to identify gaps between predictedbuilding performance and actual building performance. The dashboarddisplay 138 can be used to identify these gaps at any time during theentire building lifespan, including the planning phases, the initialconstruction phases, the operation phases, and, if applicable, thebuilding renovation phases, for new buildings, existing buildings,and/or retrofit buildings.
